so i tried again to render the scene with the glass (from the beginning of the thread) with some changes of materials and lighting, i mean simplifying it and i had a funny error (attached)

Hi Evalery,

Do you mind if we share this scene with Autodesk? We have found a strange occasional crash in this scene and it seems to be caused by the gradient texture in it.

Thanks,

Rowan

Hi Rowan,

Yes, sure please share it, it’s absolutely OK. Can you please then let me know what was the problem with the gradient, I’m just curious.

Thanks,
Cheers,

Hi,

Thank you. The problem with the gradient texture is a strange one, if it recieves a specific value from Corona it causes a crash.

Cheers,

Hi again,

I did another quick test in the same scene but changed the colours of the gradient and the colours of the materials, plus the camera angle and a few other tweaks but nothing major. So the gradient material didn’t crash with changes of colours within the gradient map, did you refer to other changes when it crashed?

I am still using the daily builds from 10 october because I did a test with the Corona 5 candidate 1 and I thought I had better results with the previous versions in terms of noise. I don’t really know why.
Anyway, this is a quick test quite lowres but i thought i got nice results in terms of the caustics now.

I can upload this version of the max scene if it helps.

thanks,
cheers,
V
